How to create Renderings in Solidworks if your ‘Render Tools Tab’ is missing

Solidworks is an extremely powerful and popular CAD program that is used to create all sorts of 3D designs for manufacture. But sometimes you’d like to create a rendered image – or rendering – to show off your design. You might need renderings for marketing presentations, portfolios, or just to test your skills and luckily …

Convert PDF to DWG – the definitive guide

DWG (drawing) files are most commonly used when working on furniture drawings, house and building architecture, and of course mechanical and industrial components. As more dimensional data, components and design features are added to a drawing, the saved DWG file format becomes too large and heavy for emailing. Therefore, it’s useful to convert it into …

Create more robust CAD models using Parametering

We spoke previously about the importance of making a CAD model more FEA friendly. A mechanical design engineer should get used to running multiple iterations of a FE analysis, making small modifications to the CAD model for each iteration. To make this iterative process much easier and faster, it is a good idea for the …

10 ways you can make your CAD models more FEA-friendly

Finite Element Analysis (FEA) is a key step in the design process. In fact, industry now commonly requires a calculation analysis sheet from design departments to approve the final virtual product. Moreover, FEA is an essential tool for developing a mechanism, calculating its lifecycle, and improving it in a number of ways. To speak of …

Meshless CAD Simulation – a new alternative to FEA

One of the main steps of the design process is simulation/analysis. During this stage the designer analyses the CAD model, assesses its limitations and improves it accordingly. Improvements typically involve adjusting design features or changing the material. This simulation is used to ensure that a design meets its mechanical requirements (e.g. stress or thermal analysis, …

Don’t get the wrong CAD hardware!

The workflow of a CAD user typically falls into 2 areas: simulation and modelling. Therefore, selecting the correct CAD workstation for your requirements is vital. If you buy hardware that’s better than what you actually need you might see the benefit of pushing the need to upgrade further into the future. However, buying something that …
